IX. Signal on Papa-urco. 



It had been determined that Papa-urco should be 

 the place where the intermediate signal betwixt those 

 of Pucaguaico and Vengotasin should be erected. 

 This mountain, which is of a middling height, we 

 ascended the i ith of August, and continued on it till 

 the 1 6th, when we returned to Pucaguaico ; so that 

 this easy mountain was a kind of resting-place be- 

 tween the two painful stations of Corazón and Pu- 

 caguaico. 



X. Signal on the mountain of Milin ; 



Whose height is nearly the same with that of the 

 Papa-urco. We ascended it: on the 2,3d of August,and 

 by the 29th had finished the necessary observations. 



XI. Signal on the mountain VenQ;otasin. 



The mountain of Vengrotasin is not remarkablv 

 high, but our stay on it was longer than we at first 

 imagined; for, after finishing our observations on the 

 4th of September, some difficulties which arose with 

 regard to the position of the following signal towards 

 the south detained us till the i8th. Plowever, the 

 town of Latacungo being contiguous to the skirts of 

 this mountain, and having several farms in its neigh- 

 bourhood, we were at no loss for many conveniencies 

 of which we were destitute in several other stations. 



XII. Signal on the mountain ofChalapu. 



Our stay on this mountain was shorter than on any 

 other in the whole series of triangles; for we continu- 

 ed only part of four days, going up the 2,oih and 

 coming down the 23d. It is none of the highest 

 mountains, and has in its neighbourhood the town 

 of Hambato, and its skirts diversified with seats and 



farms ;
